Product Overview
The Allen-Bradley 1766-L32BWAA is a MicroLogix 1400 programmable logic controller. It offers 32 digital I/O points and 6 analog I/O points. The digital I/O includes 20 inputs and 12 relay outputs. The analog I/O includes 4 inputs and 2 outputs. This controller has three communication ports. These include a combo RS232/RS485 port, an isolated RS232 port, and an Ethernet port. It supports protocols like DF1, ASCII, MODBUS RTU, DNP3, and Ethernet/IP. The built-in real-time clock provides time-based control for applications. The controller includes a built-in LCD with backlight. This allows network configuration and I/O status viewing. The controller uses 120-240V AC power. It has 20 KB memory for user programs and data. The 1766-L32BWAA supports expansion with up to seven 1762 I/O modules.
Application Scenarios
This controller suits various industrial automation tasks. Use it for machine control, packaging lines, and material handling. The Ethernet port enables remote monitoring and data exchange. The embedded analog I/O fits applications needing analog signal processing. The real-time clock helps in time-stamped data logging. The compact size allows installation in tight spaces. The controller works in clean and dry industrial environments. Over-voltage category II circuits are suitable.
